On the production and release of Hedychium coronarium essential oil from nanoformulations

Biopolymers are usually used in encapsulation techniques to protect natural products from degradation. The essential oil of Hedychium coronarium presents a floral scent, which justifies its use perfumes, addition, antimicrobial activity may contribute stability as protectant. Thus, this work aims investigate the extraction by steam distillation and enhance physicochemical through polycaprolactone, also preserving odor properties. employed nanoprecipitation process presented 1:3 optimal polymer/oil ratio, yielded an average particle diameter 159 nm. morphology was evaluated field emission scanning electron microscopy (FESEM) transmission (TEM), confirmed thermogravimetric analysis (TGA). formulations pH remained stable for 90 days controlled release compounds antioxidant analysis. diffusion were over time fitted with Peppas equation.
